Certain provisions of the Senate-passed immigration bill will have questionable interaction with the employer mandate in the Affordable Healthcare Act. The interplay of two laws could make recent immigrants 15 to 25 percent cheaper to hire than Americans.While the immigration bill exempts those given new immigration status from having coverage, the new healthcare law effectively increases the cost of hiring a new employee, which could create a disincentive for employers to hire Americans. As the bill gets turned over to the House for approval, lawmakers will have to confront the intersection of these reforms.
